Effectiveness of Psychological Treatments for Depressive Disorders in Primary Care: Systematic Review and Meta-Analysis

Abstract

PURPOSE We performed a systematic review of the currently available evidence on whether psychological treatments are effective for treating depressed primary care patients in comparison with usual care or placebo, taking the type of therapy and its delivery mode into account. METHODSRandomized controlled trials comparing a psychological treatment with a usual care or a placebo control in adult, depressed, primary care patients were identified by searches in MEDLINE, Embase, Cochrane Central Register of Controlled Trials (CENTRAL), and PsycINFO up to December 2013. At least 2 reviewers extracted information from included studies and assessed the risk of bias. Random effects meta-analyses were performed using posttreatment depression scores as outcome. RESULTSA total of 30 studies with 5,159 patients met the inclusion criteria. Compared with control, the effect (standardized mean difference) at completion of treatment was -0.30 (95% CI, -0.48 to -0.13) for face-to-face cognitive behavioral therapy (CBT), -0.14 (-0.40 to 0.12) for face-to-face problem-solving therapy, -0.24 (-0.47 to -0.02) for face-to-face interpersonal psychotherapy, -0.28 (-0.44 to -0.12) for other face-to-face psychological interventions, -0.43 (-0.62 to -0.24) for remote therapist-led CBT, -0.56 (-1.57 to 0.45) for remote therapist-led problem-solving therapy, -0.40 (-0.69 to -0.11) for guided selfhelp CBT, and -0.27 (-0.44 to -0.10) for no or minimal contact CBT.CONCLUSIONS There is evidence that psychological treatments are effective in depressed primary care patients. For CBT approaches, substantial evidence suggests that interventions that are less resource intensive might have effects similar to more intense treatments.

Efficacy and Acceptability of Pharmacological Treatments for Depressive Disorders in Primary Care: Systematic Review and Network Meta-Analysis

“…Because trials of pharmacological and psychological interventions differ greatly regarding recruitment strategies, patients, control interventions and outcomes, these trials are analyzed separately and reported in a companion article published in this issue. 17 …”

Depression in primary care: part 2—management

“…Several systematic reviews have found little or no difference in the effectiveness of different modalities of brief, time limited therapies—either low or high intensity—compared with longer term interventions such as long term psychoanalytic or psychodynamic approaches 56575859606162. A large meta-analysis of 30 studies covering 5159 participants with a range of depressive conditions from chronic subthreshold depression to MDD in the primary care setting found effect sizes in the small to moderate range for a variety of psychological therapies 62.…”

The Role of Mediators in Reducing Antepartum Depressive Symptoms in Rural Low‐Income Women Receiving a Culturally Tailored Cognitive Behavioral Intervention

“…Cognitive behavioral interventions (CBIs) have demonstrated efficacy in reducing depressive symptoms in the general adult population (Linde et al, 2015) but only one randomized controlled clinical trial (Jesse et al, 2015), has shown the preliminary efficacy of a culturally tailored CBI for reducing APDS in rural low-income and minority women with mild to moderate depressive symptoms. That trial showed similar results for African-American women at high-risk for depression.…”
